  • Publication number: 20200315815
    Abstract: An implant insertion instrument, and an implant are provided. The instrument includes a handle, a sleeve mounted to a distal end of the handle, and an implant rod disposed within the sleeve. The implant rod includes a gripper disposed on a distal end of the implant rod. The gripper has a first prong spaced apart from a second prong, the second prong being longer than the first prong. The implant includes an implant body, the implant body having a convex surface opposite a concave surface wherein an outer surface of the implant is continuous so as to prevent bone growth within the implant. Accordingly, the instrument facilitates the engagement of the implant by a simple push of the sleeve. Further, the implant has a continuous surface so as to inhibit bone growth and facilitate removal of the implant from the surgical site.

  • Publication number: 20200315814
    Abstract: An instrument and inserter kit for providing a load to insert or retract an implant 2000 is provided. The instrument includes a cover having an engagement end opposite a distal end. The engagement end is configured to mount to an engagement feature of a handle of an inserter. The cover is an elongated member having a C-shaped profile having a dimension configured to receive a sliding member. The sliding member is seated over the cover and is weighted. The sliding member is configured to slide between a first radial lip and a second radial lip so as to provide an impacting force or retracting force on the instrument.

  • Patent number: 10751093
    Abstract: A spinal screw assembly providing an adjustable securement of a fixation rod across at least two vertebrae. The assembly includes a pedicle screw having a spherical head portion, a threaded shaft portion and a tool engagement surface in the head portion for use in driving the screw into a vertebrae. The head portion of the screw is positioned in a body member adjacent a curvilinear surface disposed about an aperture in the end of the body member such that the shaft portion of the screw extends therethrough and the curvilinear inner surface abuts and mates with the head portion of the screw so as to define a ball joint therewith. The body member additionally defines a pair of opposed parallel slots therein adapted to receive a portion of the fixation rod and a locking cap bears against the fixation rod to releasably secure the rod within the assembly.

  • Patent number: 10695115
    Abstract: An expandable screw includes generally a shaft, a head, and a cut pattern. The shaft includes a longitudinal axis, an outer surface including a thread to engage bone, and an expandable region configurable between a first state with a first radius measured from the longitudinal axis to the outer surface and a second state having a second radius measured from the longitudinal axis to the outer surface. The cut pattern on the shaft permits at least partial nesting of a first portion of the expandable region within a second portion of the expandable region in the second state. The central lumen is closed by the abutment of a top portion of the second cut surface with the bottom portion of the first cut surface so as to form a closed structure or fluid seal preventing a bone ingrowth inside the central lumen.

  • Patent number: 10687861
    Abstract: An apparatus for coupling with a fixation rod to allow spinal compression, distraction, and fixation along an antero-lateral aspect of a spine includes an elongated plate, first and second fixation screws, and a first arm. The elongated plate includes a first aperture at a superior end and a second aperture at an inferior end. The first fixation screw is received by the first aperture and engages a first body portion of a first vertebra. The second fixation screw is received by the second aperture and engages a second body portion of a second vertebra. The first arm extends transversely from a first base portion on the elongated plate and includes a first hook to couple with a first portion of the fixation rod.

  • Publication number: 20200146846
    Abstract: An instrument with an implant holder disposed between a pair of tongs is provided. The implant holder may include a sleeve mechanically coupled to a distal end of a drive shaft and a pair of arms pivotably disposed within the sleeve. Movement of the sleeve in the distal direction pivots the pair of arms towards each other to grip the implant and movement of the sleeve in the proximal direction pivots the arms away from each other to automatically release the implant from the implant holder. The instrument may also include a dual mode drive shaft advancement mechanism that allows the implant holder to be advanced via an impact on the drive shaft from a tool such as a hammer or by rotation of the drive shaft.
